This book does not deal extensively with the subject matter; it states realities known to those who possess common sense, but which seem to be ignored in practice...
It was written with the intention of serving the immediate, practical, but also critical need of humans to choose and communicate with their fellow human beings, which requires some basic skills.
Today, many years after the first edition of the book, we are still amazed by the tragic disability of the Greek, both the uneducated and the most cultivated, which does not allow them to engage in dialogue.
We all, in all areas, monologue... especially in the so-called media.
Everyone speaks simultaneously without shame, despite the impressive scenes of democratic polyphony and dialogue.
